“…It is important to note that all marriages of Gypsies are only to other Gypsies, so they exist as genetic isolates. As Gypsies' origin is Asian [15], they would be expected to have a lower prevalence of PD, if genetic factors are responsible for the reported lower prevalence in the Asian population [4][5][6]21]. The estimated prevalence rate in this study for PD in Gypsies is comparable to that reported for the Asian population [4].…”

We studied the prevalence of Parkinson’s disease (PD) in Gypsies and Caucasians in Bulgaria. Cases were ascertained by examination in a clinic, a screening questionnaire and a door-to-door survey in a region of Sofia, Bulgaria. The prevalence of PD in the Gypsies was found to be 16/100,000 based on 1 case compared to 137/100,000 for Caucasians with 119 cases. It is concluded that PD is rare in Bulgarian Gypsies.

“…Ethnic differences in the prevalence of PD have become important, as genetic risk factors have been identified [1][2][3]. A lower prevalence of PD may occur among Asians and Africans than among Caucasians [4][5][6][7][8][9]. It has been suggested that Asians and Africans are partially protected against PD [10].…”

“…Several studies reported lower prevalence of PD in Africa [21,40,[71][72][73], Asia [32,46,62,[65][66][67]74] and South America [63,64] compared to Europe [16,17,19,22,25,58,60,61,75]. To facilitate comparison among 25 studies conducted in different countries, Zhang et al [76] calculated age-standardized prevalence proportions using the US population in 1970 as the standard.…”

“…The disadvantage of this technique is that often few total numbers of cases of parkinsonism are found. In addition, the case definition varies and in some instances has required the presence of tremor in order to be included as a case of parkinsonism [33,34] and thus would have excluded any non-tremulous VP patients.…”

Over the past century vascular parkinsonism (VP) has been established, dismissed and recently re-established as a possible clinical entity. We review the clinical features that have been proposed to suggest the diagnosis and explore how precisely VP has been defined on the basis of clinical, as well as radiological and pathological grounds. Estimates of the frequency of this condition have been based on population-based incidence and prevalence studies and also using case series of all types or parkinsonism. We performed a systematic search for all of these published studies and present their estimates of frequency. We conclude that the wide variations in these estimates may be largely explicable by variation in case definition. When studies are limited to those with either imaging or pathological support for the diagnosis, all but one estimate that 3–6% of all cases of parkinsonism have a vascular cause. In addition, features of parkinsonism have been seen in up to 38% of lacunar stroke patients at 1 year. On the basis of this appreciably high frequency, and with consideration of the implications for clinician and scientist, we suggest that VP needs to be recognised as an important clinical diagnosis, and includes a spectrum of distinct pathophysiological entities.
